Also see #203 where 3881dd2 went from passing to breaking (although with different behavior) on a different architecture. In both cases it has an equally older Linux userspace.

Could you please try ba32d1b and manually add -DFORCE_MONOTONIC_FIX to src/Makefile before compiling and running the tests? I assume this is related to #142 and we have no means to detect this behavior at run-time yet, so it will have to be set at compile time on the affected platforms.

fixed according to discussion in #203
